Accumulate function doesn't work at all in 5.3.0 Final

    Details

    • Steps to Reproduce:
      Hide

      1. I'm setting the stream mode to work with events (kbaseConfig.setOption( EventProcessingOption.STREAM )
      2. I have a simple DRL file

      declare StateEvent
      @role( event )
      end

      rule "Test"

      when
      Number($total : doubleValue) from accumulate(
      StateEvent(itemName=="Temperatura", $val : newState) over window:length( 5 ) from entry-point "EventStream",
      average ( ((DecimalType)$val).toBigDecimal().doubleValue() ) )

      then
      System.out.println("" + $total);
      end

      3. I insert a fact into working memory (entry point "EventStream")

      WorkingMemoryEntryPoint entry = ksession.getWorkingMemoryEntryPoint("EventStream");
      entry.insert((RuleEvent) new StateEvent(item, state));

      4. Fire rules

      5. Repeat steps 3 and 4 to put accumulate and average functions to work

      RESULTS WITH 5.2.0 Final

      Works nicely, i can see the average updated with every fact inserted.

      RESULTS WITH 5.3.0 Final

      It returns the same result and average (neither sum or the simplest case count(1)) doesn't work.

      Description

      Accumulate doesn't work in 5.3.0 Final, even the most basic cases. The same rules and code work nicely with 5.2.0 Final.
